To allwhomitmay concern:

Be it known that I, ARTHUR W. CAPS, a citizen of the United States, residing at Shawnee and State of Kansas, have invented certain new and useful Improvements in Radiators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to vmake and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

til)

This invention relates to radiators for engines and particularly to a radiator in which the heat absorbed by the water may be dissipated b air circulated in close proximity thereto w ereby the temperature of the water in the radiator may be maintained sufliciently low to be eflective as a cooling agent for gas engine cylinders and the like.

The present invention contemplates the use of a closed circulating system in which a stationary radiator and a water jacketare included, and the primary object of the in vention isv to provide means whereby a sufficient volume of air may be circulated about and through the grids of the radiator to dis sipate an appreciable'amount of the heat absorbed from the zone surrounded by the water 'acket and to this end l[ have provided a novel arrangement of fly wheel and radiator whereby the fly wheel serves as a fan or impeller to direct currents of air in radial stream lines through the radiator (circular in form and surrounding it), the advanta e of such a construction being that the y wheel serves the dual purpose of a balance wheel for the drive shaft as well as an air im eller.

have also provided means for allowing expansion and contraction of the fluid within the radiator without liability of bursting the radiator casing, this being an important feature since radiators are liable to'burst when the water therein freezes unless an expansion chamber or similar means is provided to accommodate the increased space required on account ofthe expansion due to the freezing of the liquld.

In the drawings,

I have shown the invention as applied to a known type of gas engine although it is not necessarily limited to use in connection there with. The engine selected for illustrative purposes is shown as consisting of a base block 1, on which the engine casing 2 is mounted, and provided with a combustion chamber cylinder 3 having inlet and exhaust valves operated from a head 4, the particular construction of the engine being unimportant.

Surrounding the cylinder 3 is a water jacket 5 having an inlet 6 supplied with a fluid through the medium of a circulating pump 7, the shaft 8 of which may be driven 9 of a gear 10, receiving motion from the crank shaft 11 in the usual manner.

The discharge for the chamber 12, formed by the water jacket 5 and the cylinder 3, is indicated at 13 and is shown as comprising a port near the top of the space 12, discharging into an accumulator chamber or receptacle 14,,which is normally closed by a cover 15, the cover 15 being adapted to be unseated in order to fill fluid therein needs replenishing. The bottom of the receptacle 14 is provided with a connection 16, fastened thereto by fastening devices 17 and 18. The connection 16, being tubular, discharges into a radiator casing 19, here shown as consisting of two substantially ring-shaped members 20 and 21, connected by transverse tubes or ports arranged in rows 22 and 23; The tubes of the outer row slightly alternate with those of the inner row and the tubes are shown as flat or substantially elliptical in cross section, with their sides arranged substantially tangentially to the circumferences of the radiator and the fly wheel, which the radiator surrounds. The purpose of this will be presently explained.

The tubes are also provided with radiat- I ing fans or fins 24 and 25 respectively, be-

members 20 and 21 Wlll pass into chamber 26,

from which it may be discharged into the pump 7 through the return pipe 27.

By referenceto Fig. III it will be observed that the sides of the hollow members 20 and 21 are connected by baflies 28 and 29 respectively so that water entering the radiator will follow a tortuous path back and forth through the member 21, tubes 22 and 23, member 20 and back to 21, continuing the staggered course until it reaches the chamber 26. It will further be observed that the course is divided at the connection 16 with the radiator so that the flow from the inlet to the radiator and to the chamber 26 is downward in opposite directions; thus, the water is passed over a relatively large radiating surface encompassed within a relatively small area.

I have provided means for directing a heat dissipating column of air through the ringshaped radiator which encompasses the fly wheel 30, the periphery of which closely approximates the inner circumference of t e radiator 19. The fly wheel is shown as fast on the crank shaft 11 and has a closed back 30, provided with a rim having a plurality of impeller blades 31, alternating with inwardly projectin long and short blades 32 and 33. The blades 33 are co-extensive with some of the impeller blades 31 and consist of ribs cast inte ral with theclosed back of the fly wheel an with the inner portion of blades 31 and extend to the hub of the fly wheel. The blades 32 are short and alternate with the blades 33 but assist in directing air through the rim of the fly wheel in stream lines through the radiator.

The impeller blades 31 are provided with curved faces 34, which direct currents of air from the axis of the fly wheel through the rim thereof and in radial but slightly tangential directions to pass between and over the tubes 22 and 23 of the radiator in such a manner as to effect the most eflicient radiation or heat dissipation of the fluid passing through the radiator.

The chamber 26 serves not only as an accumulator chamber for the water passing through the radiator before it is re-introduced to the cooling chamber 12, but it also allows for expansion of the liquid without liability of disrupting the system. For example, when the engine is cold, the water is liable to freeze in the radiator but the chamber 26 is of suflicient capacity to allow for expansion in case of freezing so that liability of the radiator bursting will be eliminated.

From the foregoing description in connection with the drawings, it will be apparent that the circulating system for dissipating the heat generated in the engine cylinder can be conveniently attached to the engine, that the parts are easily detachable for the purpose of inspection and repairs, and that the construction is well adapted to perform the functions for which it is intended.

What I claim and desire to secure by Letters-Patent is:

1. A radiator comprising a substantially cylindrical casing having oppositely disposed compartments, flat tubes transversely connecting said compartments and arranged tangentially to the circumference of the radiator, and an air impeller within the radiator for directing air in stream lines parallel to the walls of the tubes.

2. A radiator comprising a substantially I ring-shaped body member having compartments, tubes connecting said compartments, an expansion chamber at the bottom of the body member, and an air impeller within the ring-shaped body member for directing air outwardly throu h the spaces between the compartments and over the tubes.

3. A radiator element comprising a pair of chambered rings, tubes rigidly connecting said rings and opening into their chambers to provide communication therebetween, and a fly wheel rotatable within the radiator element and having means for directing air in radial lines through said radiator element.

4. A radiator element comprising chambered rings, tubes connecting said chambered rings and opening into the chambers thereof,

and an expansion chamber communicating with said chambered rings.

In testimony whereof I aflix my signature.
